Running head: HOW does saLT AFFECT THE BOILING POINT OF WATER? 1 How Does Salt Affect the Boiling Point of Water? Elizabeth Mompoint Everglades High School HOW does saLT AFFECT THE BOILING POINT OF WATER? 2 Abstract The purpose of this experiment was to determine whether or not salt would affect the boiling point of water. Much of the research I conducted rejected my hypothesis which stated: if I add salt to water‚ then the boiling

Objective 1. Use the analytical balance to weigh a given hydrated salt as accurate as possible in order to determine the weight of water in the salt Introduction Balances are important laboratory equipment as they are used to determine the mass of materials. Today‚ most balances used in the laboratory are analytical balances which can give readings up to four decimal places or higher. High accuracy is needed in certain experimental work such as material analysis or those involving small change

plants growth. In general‚ watering with different liquids has been bad for plants and has damaged their growth. For instance‚ adding salt or sugar to plants can change the growth of a plant. In general‚ salt usually hurts a plant. According to djrice69‚ a poster on Flowerhorn USA‚ an online forum‚ there is already a concentration of salt in the soil. When more salt is

How I Got to Salt Lake Community College I always wanted to go to college growing up‚ but because of my family‚ along with my sisters and myself‚ were born and raised in a refugee camp in Nepal‚ I had a feeling that college was a dream that would not come true for me. In 2012‚ we came to Salt Lake City‚ Utah. The school I did was from 9th grade. After resettlement in the United States‚ my parents are still struggling to look after the educational future of me and my sisters. My family said if I

Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Gracen Seiler April 7th‚ 2015 Section- 109 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction- This experiment is intended to help find a better understanding of chemical stoichiometry through titrations of NaHCO3 and NA2CO3 with HCl. A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form in a nuclear reaction. Titration is when a measured amount of

Research Question: How can different masses of salt affect the percentage of transmitted light? Variables – Independent – • Mass of salt‚ the salt added into the distilled water in grams (0.1‚ 0.5‚ 0.75‚ 1‚ 1.5) Dependent – • Percentage of transmitted light through the solution using 5 different mass of salt and a constant availability of 2g of sugar as source of food. (there are 5 trails for each conical flask representing 5 different salt masses) Controlled – What is being Controlled

would form better between sugar and unionized salts. Also under two different temperatures‚ would this effect the size at all. My overall hypothesis was to test at what rate and size would crystals grow in sugar vs salt at different temperatures‚ and that I thought the salt would produce a greater amount of crystal deposits. My method was hanging a string from a pencil immersed in the different solutions. My results were similar in both tests. Both the salts in the temperatures grew small amount of crystals

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and
